Harry Reid's letter to James Comey!

Last August, Senate Minority Leader Harry Reid sent James Comey a fiery letter saying the FBI chief may have broken the law and pointed to a potentially greater controversy: "In my communications with you and other top officials in the national security community, it has become clear that you possess explosive information about close ties and coordination between Donald Trump, his top advisors, and the Russian government…The public has a right to know this information."

Reid's missive set off a burst of speculation on Twitter and elsewhere. What was he referring to regarding the Republican presidential nominee? At the end of August, Reid had written to Comey and demanded an investigation of the "connections between the Russian government and Donald Trump's presidential campaign," and in that letter he indirectly referred to Carter Page, an American businessman cited by Trump as one of his foreign policy advisers, who had financial ties to Russia and had recently visited Moscow. Last month, Yahoo Newsreported that US intelligence officials were probing the links between Page and senior Russian officials. (Page has called accusations against him "garbage.") On Monday, NBC News reported that the FBI has mounted a preliminary inquiry into the foreign business ties of Paul Manafort, Trump's former campaign chief. But Reid's recent note hinted at more than the Page or Manafort affairs. And a former senior intelligence officer for a Western country who specialized in Russian counterintelligence tells Mother Jones that in recent months he provided the bureau with memos, based on his recent interactions with Russian sources, contending the Russian government has for years tried to co-opt and assist Trump—and that the FBI requested more information from him.

"This is something of huge significance, way above party politics," the former intelligence officer says. "I think [Trump's] own party should be aware of this stuff as well."

Does this mean the FBI is investigating whether Russian intelligence has attempted to develop a secret relationship with Trump or cultivate him as an asset? Was the former intelligence officer and his material deemed credible or not? An FBI spokeswoman says, "Normally, we don't talk about whether we are investigating anything."
